Lush green rice terraces sprawl over 2,200 hectares of mountainside ready to be harvested. These stunning images, captured by photographer Saravut Whanset, show the incredible terraces throughout the course of the day, including at sunrise and sunset. Workers tend to the fields, with each terrace between 1 and 1.5 metres wide, while wooden huts stand on stilts on the mountainside.
